Tip for last badge. When you kill the first head, make sure you do it when it is just about to fire the eye-laser-beam from the side. Then move to middle ladder and keep whakking it while it transforms. Then just continue whakking it until it dies. This way the skull gets stunned to corner and you can whack him to death whitout it even fiering those fireballs even once.
